15.5 FREQROL Series Inverter Side Settings

For details of the inverter, refer to the manual of each series.

15.5.1Connecting FREQROL-S500, S500E, F500J series

Communication settings

Make the communication settings of the inverter.

Be sure to perform the inverter reset after updating each parameter.

(2)Communication settings of inverter

Set the following parameters using the PU (parameter unit). Set Pr.30 (Extended function selection) to 1 [With display] before making the parameter settings.

Do not change these parameters, even though they can be monitored from the GOT. If they are changed, communication with the GOT is disabled.

*1 Setting items are parameter names described in the manual of FREQROL-S500, S500E, and F500J series.

*2 Settings on the GOT can be changed.

When changing the settings on the GOT, be sure to change the parameters on the inverter to correspond with the GOT settings.

*3 Inverter default values (No need to change)

*4 When being monitored from the GOT, the parameter n1 through n7 correspond with Pr.331 through Pr.337, and the parameter n10 through n12 correspond with Pr.340 through Pr.342.

Numbers in brackets show the parameter number when the parameter unit is in use.

*5 There is no Protocol selection setting on the inverter side.
